Class 6 Maths Chapter 5 Prime Time and Properties
Class 6 Maths Chapter 5 introduces prime numbers, explaining their properties and importance in number theory. It covers the fundamental concept that prime numbers have only two factors: 1 and themselves. This knowledge is crucial for MCQs, as questions often ask students to identify prime numbers within a given range, determine the total count of prime numbers up to a certain number or differentiate between prime and composite numbers. NCERT Class 6 Maths Chapter 5 also explains the Sieve of Eratosthenes, a useful method for finding prime numbers, which can be directly tested in multiple-choice questions.
Q2. What should players say in the Idli-Vada game for the first common multiple of 3 and 5?
Class 6 Maths Chapter 5 Factors and Multiples
Another essential aspect covered in Class 6 Maths Chapter 5 is factors and multiples, including common factors and common multiples. NCERT Class 6 Mathematics Chapter 5 is helpful for MCQs that require students to find the greatest common divisor (GCD) or least common multiple (LCM) of two or more numbers. Class 6 NCERT Math Chapter 5 provides engaging activities like the Idli-Vada game, which helps reinforce the understanding of multiples. Many competitive and school-based exams include MCQs where students have to quickly determine if one number is a multiple of another or find the first few common multiples of two numbers.
Q3. Which of the following is not a factor of 56?
Q4. What is the prime factorization of 72?
Prime Factorization in Class 6 Maths Chapter 5
Class 6 Maths Chapter 5 describes about prime factorization, teaching students how to break down numbers into their prime components. This is a fundamental concept for solving MCQs that involve determining the prime factorization of a number, identifying the highest power of a prime in a factorial or solving word problems related to divisibility. Since many standardized tests include direct or application-based MCQs on prime factorization, understanding this method enhances problem-solving efficiency.
Co-prime Numbers in 6th Maths Chapter 5 Prime Time
An important sub-topic is co-prime numbers, which are numbers that have only 1 as their common factor. Class 6 Maths Chapter 5 explains how to determine whether two numbers are co-prime by finding their greatest common factor. MCQs related to co-primes often ask students to select pairs of numbers that are co-prime, find the smallest co-prime number with a given number or apply co-prime properties in problem-solving. This knowledge is also useful in probability-based MCQs where co-primes are used in determining relative primes in a given set.
Q8. A composite number is one that has
Class 6 Maths Chapter 5 with Divisibility Rules
NCERT Class 6 Maths Chapter 5 introduces divisibility rules for numbers like 2, 3, 5, 10 and more. These rules are particularly helpful in MCQs where students must determine whether a given number is divisible by another without performing lengthy division. Quick mental calculations using divisibility rules help in time-constrained exams, making it easier to eliminate incorrect choices and arrive at the correct answer. Many exams include MCQs that ask students to apply these rules to find missing digits in numbers or determine which numbers satisfy multiple divisibility conditions.
Q9. What jump size will let Jumpy land on both 15 and 30?
Q10. How many prime numbers are there between 1 and 10?
Class 6 Maths Chapter 5 Prime Time builds a strong foundation in number properties, primes, factors and divisibility—key concepts for solving MCQs efficiently. The exercises and games included in the chapter make learning interactive and engaging, while the structured explanations provide clarity for answering multiple-choice questions accurately. Understanding these concepts not only helps in mathematics exams but also strengthens logical reasoning skills for competitive tests.
How can I determine a prime with the help of Class 6 Maths Chapter 5?
As per Class 6 Maths Chapter 5, a number is prime if it has exactly two factors: 1 and itself. To check if a number is prime, divide it by prime numbers up to its square root. If it is not divisible by any of these, it is prime. NCERT Class 6 Maths Chapter 5 also introduces the Sieve of Eratosthenes, a systematic method to identify prime numbers up to a given limit.
How does Class 6 Maths Chapter 5 differentiate between prime numbers and co-prime numbers?
According to Class 6 Maths Chapter 5, a prime number has only two factors: 1 and itself (e.g., 2, 3, 5, 7). On the other hand, co-prime numbers are two numbers that do not have any common factor other than 1 (e.g., 8 and 15, 21 and 22). Co-prime numbers do not need to be prime themselves.
How can prime factorization help in solving Class 6 Maths Chapter 5 MCQs?
Prime factorization breaks a number into its prime factors, which helps in solving MCQs related to LCM, GCD, divisibility and co-prime numbers. Many exams include MCQs asking students to find the highest power of a prime in a factorial, determine divisibility or compare numbers based on their prime factors.
